ah yes see what you mean, I tried the links at the top of the page but they're dead. I had V12 installed and ended up following the trail to get 8.8.3 version.
Thanks for the link, I have downloaded the batch replace script which defiantly wasn't in the v12 or 8.8.3 install zip's so no idea where that went

Any way I have ran the replace_dlls script (with Admin cmd prompt) but still no change (no video, no sound) looking at the script and doing a search for the msvidctl.dll & cpfilters.dll on my PC shows about 6 versions of the files dotted around (c:\windows\system32, c:\windows\winsxs, c:\windows\syswow64 and the memorable folder: C:\Windows\WinSxS\amd64_microsoft-windows-video-tvvideocontrol_31bf3856ad364e35_10.0.18362.1_none_c10dba5b005177b0) which none had changed versions

I ran the script again which I don't think threw up any errors but as the window only appears for a few seconds I had to record it on my phone to watch in slow mo. I noticed I didn't have the tool nsudo, so downloaded it of majorgeeks added to the install bin folder (remembered to unblock it) and still no luck, I even rebooted!!!

so ran the uninstall ran the installer with the thumbnails & replace dlls and bish bash all working again.

The dlls required by MWC are in the bin folder of the zip file and nsudoc is in the bin folder of every installer, which is why I say to unzip it into the installer folder so that all the cmd files are together and all the bat files are together in the folder below.

You shouldn't need to download anything else as long as you unzip it in the right place.

if you have already run WMC, the DLLs may be in use so it might need a reboot before it works.

Since 9 July the DVB-T signal in the Netherlands has been changed to DVB-T2 and my USB stick (DVB-T) is no longer working.
I have bought a new USB stick with DVB-T, T2 and C signal (AVerMedia AVerTV HD310).
This USB stick works great with the AVerTV 3D program, but not with WMC.
After more than 12 hours of scanning for channels, the process remained at 97% after almost 2 hours, and no channel had yet been found.
The USB stick is recognized and specified in WMC.
Can someone tell me if WMC can handle the DVB-T2 signal?
And if WMC can do that, can you tell me how to do that.
I would like to work with WMC again.
I downloaded and installed the latest version of WMC-V13 (64-bit) via the shortcuts of message #23.

If you’ve installed all the AverMedia software (their tv software etc) uninstall it all and try just installing the driver - right click the .sys file in driver folder and install. Reboot and run WMC setup again. I had an aver tuner many years ago and the software seemed to take control of the device and not allow it to function fully with other software.
It’s been a while so might not still be the case. But worth a try.

aquadextrous, I tried what you said.
Unstalled the AVerTV 3D program and drivers for the AVerTV TD310.
And only installed the driver via the .inf file: AVer1871.inf, but the result is the same.
No channel is found after about 35% scanning and more than 2 hours later.
And scanning so long for a few channels is not a good sign.
While with the AVerTV 3D program after 22% scanning and less than 2 minutes later, 9 channels have already been found.
All I have to do is to try a completely clean installation of Windows and WMC.
Thanks in any case for your help.

But for the sake of clarity, I only installed the AVerTV 3D software after it turned out that WMC not found any channel during scanning.
And to rule out that the TD310 TV Tuner was defective, I installed the AVerTV 3D software.
And it works well, just recording programs is extremely bad.
And the operation of WMC is also much better.

I've done some reading and I think this is actually pretty complicated.

I suspect that, not only has DVB-T been switched off, but the frequencies that the DVB-T2 channels are being transmitted on are different to the ones that were used for DVBT. There is mention of changes being made in conjunction with neighbouring Countries to free up the 700Mhz band. We went through a similar process on our terrestrial TV here a while back.

So I have a feeling that you are coming up against an issue with the age of the tuning data that Windows Media Center downloads when you first configure it.

This is a major problem for me because I use a couple of old PCI DVB-S2 cards in my Living Room PC, which are connected to three LNBs through diseqc switches behind the dish. The tuning data that WMC downloads doesn't seem to have been updated for years so the first time I do a scan, I get about a third of the channels that are available. I then have to manually add or amend the details for every transponder and rescan for channels. If the transponder is sending DVBS2, then I also have to add or amend the registry entries for that transponder as well. All the newly added channels have completely arbitrary numbers and I have to manually renumber everything that works and remove anything that doesn't. Multiply that by three satellites (for a total of about 7300 channels altogether) and you can see why I don't ever want to set up my system from scratch.

Anyway, enough about my problems and back to yours!

The problem for you is that you can't do a manual scan or alter the frequencies that WMC is looking for.

So, why does the Avermedia software work? I wouldn't mind betting that it does blind tuning (scanning every frequency the tuner can tune to and looking for a signal) rather than only tuning in certain predefined frequencies. It probably autoconfigures itself to the signal that it is receiving as well rather than having to be told what every channel is expected to be.

Technodevotee, thanks for your help and sorting out.
I had read something similar myself and also that the signal has been changed to make room for the 5G frequency that they are going to apply.
So it seems that WMC will gradually no longer be usable and that would be a great pity.

There might be someone who knows more about the tuning mechanism used by WMC. For example, Gary, who created EPG123 may be able to help. It used to be possible to edit and add channels once with a tool I had and I actually added a custom channel once when I couldn't get it to work but it stopped working and just started giving errors. Can't think of the name of it for the life of me.

The other hope of course is that Microsoft update the tuning information for your location.

Technodevotee, yesterday i installed the program NextPVR v4.2.4 buil 190307. (most recent version)
This program also recognizes the Dutch DVB-T2 signals and scans all channels that can be found in my area.
The frequencies and SID are also given, as examples: NPO1 - Freq: 722000 SID: 710, NPO Radio 1 - Freq: 722000 SID: 7110.
I can optionally provide a list of all channels, with frequencies and SIDs found by NextPVR on my computer.
Fortunately I can now watch normal TV again and record well, but WMC still remains superior to all the other programs I know.
So if it is possible to work with WMC again, that is a great outcome.
Microsoft makes a lot of rubbish, but WMC was and remains a great product.
Maybe that is why they no longer support and innovate it, because they don't like good products there, I believe.
And many thanks for all your help.

BMV - Microsoft don't want us watching free TV, they want us to buy stuff from their store.

I also use NextPVR (in the UK) - reluctantly, I had to give up on WMC because MS seem to deliberately break it every 6 months and it was getting tiresome fixing it. In fact, the only thing that seems to change with every so-called Windows 10 new version is that WMC gets disabled.

Technodevotee, thanks for the information, and only the 64-bit version is not really a problem.
But where can I find Kevin Chalet's WMC V8.8.4?
On the web I only find the WMC V8.8.3, and only information about V8.8.4 that it is comming soon.

Technodevotee, Kevin Chalet's version 8.8.4 also gives the same result.
But I have read that he is working on 8.8.5 with more changes, so wait and see if that version will work with the DVB-T2 signal in the Netherlands.
Thanks for everything.
